CONCRETE-MIXER.

Specification of Letters Patent.

Patented Nov. 1, 1910.

Application filed July 28, 1910. Serial No. 574,326.

1'0 all whom it may concern:

Be it known that 1, JOHN Mneenns, a citizen of the United States, residing at Charlotte, in the county of Clinton and State of Iowa, have invented a new and useful Concrete-Mixer, of which the following is a specification.

It is the object of this invention to provide, in a simple, merchantable and inexpensive form, a mixing machine for the manipulation of cement and concrete, the construction of the device being such that the plastic mixture will be thoroughly agitated and moistened during its agitation.

Another object of the invention is to provide a cement mixer, the beater of which is provided with a series of adjustable blades, the blades being so mounted that the angle between them and the axis of the beater, may be changed at the will of the operator.

'Yet another object of the invention is to provide novel means whereby water may be mingled with the contents of the container, during the agitation of its contents.

Another object of the invention is to provide novel means for supporting a source of water supply, and to provide novel means for receiving water from said source of supply, and for dispersing the same within the container.

In the accompanying drawings,-1*igure 1 is a top plan, parts being broken away; Fig. 2 is a side elevation; Fig. 3 is a transverse section on line A-B of Fig. 2; Fig. 41 is a detail perspective of one of the blades; and Fig. 5 is a transverse section of the shaft.

The frame upon which the working portions of this machine are mounted, includes legs 1, suitably braced at 2. A container 3, preferably a trough-shaped element, is secured between the legs 1. Adjacent one end, the container 3 is provided with a transverse partition 5, to which is secured an inclined chute 4, whereby stone, cement and sand, may be introduced into the container 3.

Transverse bearings 6 are mounted in the container 3, adjacent the ends thereof, and in these bearings 6, the beater is journaled for rotation. This beater includes a shaft 8, the diminished ends 7 of which are rotatably mounted in the bearings 6. At one end, the shaft 8 carries a wheel 9, the periphery of which is adapted to receive a belt,

whereby the device may be operatively connected with a prime motor. The wheel 9 carries an outstanding handle 10, so that each include an outstanding flange 12, and a shaft-engaging flange 14, the flanges 12 and 14: preferably, although not necessarily, being disposed at right angles to each other. In the shaft-engaging flange 1 1 of the blade 11, there are a plurality of openings 15, disposed in the arc of a circle, the center of which circle is a threaded member 17, removably inserted through the shaft-engaging flange 1 1 of the blade 11, and threaded into the shaft 8. A projection of some sort, for instance, a pin 16, outstands from the shaft 8, this pin 16 being adapted to enter the openings 15, successively, as the blade 11 is rotated upon the retaining member 17.

It will be seen that by successively engaging the pin 16 in the openings 15, the angle between the outstanding flange 12 of the blade and the axis of rotation of the shaft 8 may be altered, the thrust of the outstanding flange 12 of the blade being changed accordingly. This successive engagement between the pin 16 and the openings 15 may be secured by loosening the retaining member 17 in the shaft 8, and obviously, by rotating the retaining element 17 to a firm seat, the retaining element will act as a clamping device, adapted to hold the interlocked elements represented by the holes 15 and the pin 16, in engagement.

Secured to the outer face of the container 3, and disposed longitudinally thereof, is a bar 18', spaced apart in its intermediate portion from the container. A bracket is included, the bracket comprising le s 19 and a platform 23. The legs 19 are inc ined, their lower ends 20 being slidably engaged between the bars 18 and the container 3, their upper ends 22 being secured to the platform 23, adjacent the outer edge of the platform. Transverse braces 21 unite the legs 19. The inner edge of the platform 23 is provided with a distributor 24, this distributer being preferably a trough-shaped structure, formed integrally with the plat form 23, or connectin therewith in any desired manner. This istributer 24 is perforated as denoted by the numeral 25. The distributor 24 overhangs the upper edge of the container 3, and serves incidentally as a means for retaining the bracket braced upon the container.

The bracket is adapted to support a tank 26, or other source of Water supply, the tank 26 being, if desired, provided With a cock 27. This cock 27 is positioned to discharge into the distributor 24:, the primary function of the distributer 24 being to receive the Water from the tank 26, and to distribute the Water, through the perforations 25, through the mass which is being agitated Within the container 3.

The bracket, it is to be noted, may be slid longitudinally of the container 3, and thus the Water may be introduced into the mass Within the container 3, at any desired point between the chute 4 and the discharge end 28 of the container 8.

By reason of the fact that the blades 11 may be adjusted to regulate the rapidity with which the concrete is forced through the container 3, together With the fact that the distributer 24 may be slid longitudinally of the container 3, the amount of agitation Which the concrete Will receive, before the Water is introduced thereinto, may be adjusted to a nicety. Thus, the adjustable blades 11 and the slidable distributor 24: cooperate in producing a mixture of the desired consistency.

Having thus described the invention What is claimed is 1. In a ClGVlCQOf the class descrlbed, a contamer; a mixer ournaled 1n the container, and comprising a shaft and a blade thereon, in one of which there is a plurality of openings disposed in an arc of a circle, and in the other of which there is a projection to register successively in the openings, thereby to change the angle of the blade With respect to the axis of the shaft; a clamping device located at the center of the arc in which the openings are disposed, the clamping device constitutin at once a pivotal mounting for the blad e, and a means for holding the blade upon the shaft to maintain the projection successively in the openings.

2. In a device of the class described, a container; a bar securedto the container longitudinally thereof; a bracket including a leg slidable upon the bar, and a platform upheld by the leg and adapted to support a tank, the platform being provided along its inner edge With a trough-shaped distributer extended longitudinally of the container and adapted to receive the contents of the tank, the distributer overhanging and engaging slidably with the upper edge of the container to prevent the bracket from tilting away from the container.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of tWo Witnesses.

JOHN MEGGERS.
